Reaction Steps

To a suspension of (2E)-3-{6-[(1-benzoyl-4-piperidyl)amino]-3-pyridyl}acrylic acid (170 mg) in DMF (3 ml) was added O-(tetrahydro-2H-pyran-2-yl)hydroxylamine (62.3 mg), EDCI HCl (102 mg), HOBt (71.9 mg), Et3N (0.201 ml), the mixture was stirred at 23° C. for 8 hours. The mixed solution was poured into a mixture of water (20 ml) and AcOEt (20 ml). The organic layer was separated, washed with water twice and brine, dried over sodium sulfate and concentrated in vacuo. The residue was purified by silica gel column chromatography eluted with 8% MeOH in dichloromethane to give (2E)-3-{6-[(1-benzoyl-4-piperidyl)amino]-3-pyridyl}-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (50 mg).
